2 Claims. (Cl. 158-lt'i5) 4 heating devices a centralized valve mechanism with remote control. This structure results in a saving of space, as. well as material and labor in construction. It also effects economy in the use of gas and increased heating efiiciency, since '10 the heated air below the utensils placed upon the burners is drawn into the latter through the mixing valves.

It is another object of my invention to provide a gas burner control unit having a minimum number of valves and connections, thus affording less chance for the hazards of leakage.

Another object of my invention is to provide a gas burner control unit that can be made uniform to fit any gas stove, and which can be manufactured to accommodate two or more burners.

Other important and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claims.

In the accompanying drawing illustrating my invention, Figurel is a plan view of a gas range or heating device employing my standard valve mechanism with remote control. Figure 2 is a sectional plan view of the centralized valve mechanism. Figure 3 is a sectional view taken on the line 3-3 of Figure 2. And Figure 4 is an end view of the controls employed by my valve mechanism.

Referring to the accompanying drawing illustrating my invention, the numeral 1 designates a gas stove controlunit body of substantially rectangular contour and" constructed of malleable radially from the corners of the body 1 are threaded bosses 2 which receive adjustable nozzles 3 by which burners 4 are connected to the body.

Gas is admitted to the hollow body 1 through an inlet 5 connected with a supply main (not shown) by a tube 6. Since the valve mechanism is in the central portion of the heater, air entering the mixing valves of the burners will be thoroughly heated to promote fuel economy and increased heating eflicinecy. V

For the purpose of remotely controlling the flow of gas to the burners from the valve body 1,

there are formed within the latter two alined bosses 7, 7 provided with tapering bores 8, 8

whose larger ends extend outwardly through outer boss portions 9, 9 on the body The walls of the body 1 are formed with passages 10, 11, 12 and 13 which lead from the burner-connection receiving portions 2 to the valve bores 8, 8. In the latter are rotary tapering valves 1.4 and 15 open at their inner ends to the valve body, the valve 14 being formed with ports 16 and 17 which communicate with both the gas passages 10 and 13 when it is desired to supply gas to two of the burners at the same time.

The valve 14 is also provided with ports 18 and 18 on diametrically opposite sides, and in circumferential alinement with the ports 16 and 17, to register respectively with the passages 10 and 13 to deliver gas to a rear or front burner on that side of the heater.

The valve 15 is formed with ports 19 and 19 on diametrically opposite sides, whereby it may be turned to bring the port 19 into registry with the passage 12 to supply gas to the front left burner, or it may be rotated to bring the port 19 into registry with the passage 11 to deliver gas to the rear left burner. The valve 15 is also formed with ports 20 and 21 in circumferential alinement with the ports 19 and 19 that are adapted to register simultaneously with both the passages 11 and 12 if two burners on that side of the heater are to be used at the same time. a Each valve is formed with a stem 22 that projects through a nut 23 applied to the threaded outer boss 9 on each side of the body. A coil spring 24 surrounds each valve stem between 88 the nut and a thin brass washer 25 on the head of the valve to hold the latter against its seat.

Secured to the outer end of each valve stem 22 is an operating tube 26 that passes through a hole in the front plate 27 of the range. Attached to the front end of each tube is an operating knob 28, and to the inner face of the latter there is secured by screws 29 a' disc 30 formed with a pointer end 31. Secured to the front plate 27 behind this disc is a fixed circular indicator 32 bearing the words: Ofi, Rear, Rear and iron and Front.

Formed in the top of the body 1 is a threaded hole 33 to receive a pilot light (not shown) by which the burners may be ignited in a conventional manner.

In Figure 4 the right pointer 31 has been turned to the words, Front and rear, with the result that in Figure 2 the valve 14 has a position in which both the ports 16 and 1'7 are in communication with the passages 10 and 13 to deliver gas'to both'right' front and rear burners. A turn of the pointer to the Rear position will rotate the valve 14 to a position in which the port 110 18 will register with the passage 10 to cause a delivery of gas to the right rear burner alone; while the right front burner will be the only one on that side of the body to receive gas if the right knob 28 is turned to bring the pointer to the Front position.

Similar results will be obtained on the left side of the body by rotating the left knob .28 to bring its pointer 31 to the Front and rear, Rear and Front positions on the fixed dial 32. By bringing the pointer 31 to the Off position of the fixed dial on each side of the body, the valve corresponding to the knob rotated will be brought to a position in which no one of its ports will be in communication with a burner passage, thus shutting off the flow of gas to all of the burners from the hollow reservoir within the body.

By using my centralized control unit; one gains a simplified construction in which the hazard of gas leakage through multitudinous couplings is eliminated. Furthermore, while cold air is drawn into the conventional burner at the front of the stove or range, in my type of centralized-control unit air heated below the utensils placed upon the burners is drawn into the latter through the mixing valves to increase heating efficiency as well as economy in fuel consumption.

Having described my invention, I claim:

1. In a gas heating device, a hollow gas-receiving body of substantially rectangular contour, centrally mounted on the top thereof, said body having four ported corners, radially disposed burners communicating with the ported corners of said body and closely adjacent thereto, a gas' supply pipe projecting from one side of the heating device between two of said burners to said hollow body, two rotary-ported valves within said body for controlling the flow of gas therefrom to the burners, and a stem for each valve, and an operating sleeve connected to said stem and projecting through the front of the heating device.

2. In a gas heating device, a hollow gas-receiving prismoid body centrally mounted on the top thereof, radially disposed burners communicating with said body and closely adjacent thereto, two hollow bosses formed within said body, one at each inner corner thereof immediately behind the front of said heating device, two gas conducting passages leading from each boss to two respective points of connection of two burners to said body, a rotary-ported valve in each hollow boss to control the flow of gas from said body to the respective burners, and remote control means for said valves at the front of the heating device.
